“…Some research has been performed on bio-oils to detect the specific molecular weight distribution. Bio-oil compounds had molecular masses in the range of ~100-800Da, while the petroleum or heavy petroleum fractions had narrower m/z range [42]. So it is reasonable that the AVMZ increases when more SD was blended in feedstocks.…”

Microwave-assisted co-pyrolysis of oil sands and biomass (sawdust) was carried out for the first time to investigate the synergistic effect under microwave irradiation. In the co-pyrolysis process, the pyrolysis residues of sawdust serve as the effective microwave absorber to enable the improved thermal decomposition of oil sands compared with the case by the conventional thermal treatment. Effects of co-pyrolysis temperature, blending ratio, and feedstock-tomicrowave absorber ratio on the product distribution were examined. Compared with conventional (CV) co-pyrolysis, a synergetic effect, in terms of 10.9wt.% higher gas yield and 8.3wt.% lower liquid yield, was manifested during microwave (MW) co-pyrolysis. Biomass added to the feedstock promoted the generation of compounds with molecular weight >800 Da in the liquid products. MW radiation promoted 24.5 % higher aromatic hydrocarbons on average, but 19.2% fewer phenols in MW-generated oils, which are more desirable as value-added chemicals. Furthermore, chars produced by MW performed more porotic, contributing to positive recycling as absorbing materials. The thermochemical conversion of biomass with oil sand revealed that MW heating is a simple, effective, and alternative solution to increase the energy efficiency of co-pyrolysis process, maximizing the use of resources.

I am very pleased that you will consider our manuscript for publication in Fuel. Furthermore, we thank the reviewers for their valuable comments on our manuscript entitled "Insights into the synergetic effect for co-pyrolysis of oil sands and biomass using microwave irradiation". All the comments are very valuable and helpful for revising and improving our paper. We have considered the comments carefully and made more appropriate corrections which we trust to meet your approval. Revised portions are marked with red text in the paper. The detailed corrections in the paper and the responses to the reviewers' comments are listed point by point hereafter. Answers to reviewers' comments Reviewer 1 Comments: The author did interesting work carring out the microwave-assisted co-pyrolysis of oil sands and biomass firstly. Co-pyrolysis resulted in a higher gas yield and lower liquid yield than the single-material pyrolysis. The yields of MW-generated volatiles were higher than CV-generated volatiles. Thermal decomposition behavior and determination of the final temperature, determination of additives, oil composition analysis and characterization of chars are investigated with different oprating conditions. This article provides a new route for the utilization of biomass, which has significant consequence. Author reply: We thank the reviewer for the positive feedback and the constructive comments. Comment 1: The English expression should be c...

“…In order to have a clear idea about how the proposed analytical technique can be complementary to modern HRMS techniques offering very high resolving power, we compared SFC-HRMS to FT-ICR/MS (Fourier transform-ion cyclotron resonance mass spectrometry) for the specific case of bio-oil analysis. Since several years, HRMS techniques alone are being increasingly used to describe the composition of biomass fast pyrolysis oils [3]. In particular, FT-ICR/MS has gained in interest over the past ten years, providing key information in terms of m/z ratios, molecular formulae and double bound equivalent (DBE) for compounds being detected essentially by electrospray ionization source, and more scarcely by APPI [20][21][22][23][24][25].…”

“…For further uses as biofuels or bio-based products, upgrading is necessary which can be only achieved if a detailed characterization is available. Recent publications present a comprehensive overview of current analytical techniques used to characterize pyrolysis biooils [2][3][4]. It is pointed out in both papers that high resolution mass spectrometry (HRMS) has become the primary method for the analytical characterization of bio-oils, considering its potential to determine both the molecular weights and the elemental compositions of thousands of bio-oil compounds [3].…”

“…Electrospray ionization (ESI) and Atmospheric Chemical Ionization (APCI) are commonly applied ionization techniques, mostly operated in negative ionization mode. According to Stas et al [3], a distinct advantage of negative-ion APCI is that it can detect some more unsaturated, less polar bio-oil compounds with higher carbon numbers and m/z range not detectable by negative-ion ESI. In spite of its impressive analytical power, two key issues arise from the use of HRMS as single analytical technique.…”

Extensive characterization of complex mixtures requires the combination of powerful analytical techniques. A Supercritical Fluid Chromatography (SFC) method was previously developed, for the specific case of fast pyrolysis bio oils, as an alternative to gas chromatography (GC and GC × GC) or liquid chromatography (LC and LC × LC), both separation methods being generally used prior to mass spectrometry (MS) for the characterization of such complex matrices. In this study we investigated the potential of SFC hyphenated to high resolution mass spectrometry (SFC-HRMS) for this characterization using Negative ion Atmospheric Pressure Chemical ionization ((-)APCI) for the ionization source. The interface between SFC and (-)APCI/HRMS was optimized from a mix of model compounds with the objective of maximizing the signal to noise ratio. The main studied parameters included both make-up flow-rate and make-up composition. A methodology for the treatment of APCI/HRMS data is proposed. This latter allowed for the identification of molecular formulae. Both SFC-APCI/HRMS method and data processing method were applied to a mixture of 36 model compounds, first analyzed alone and then spiked in a bio-oil. In both cases, 19 compounds could be detected. Among them 9 could be detected in a fast pyrolysis bio-oil by targeted analysis. The whole procedure was applied to the characterization of a bio-oil using helpful representations such as mass-plots, van Krevelen diagrams and heteroatom class distributions. Finally the results were compared with those obtained with a Fourier Transform ion-cyclotron resonance mass spectrometer (FT-ICR/MS).

Rationale:The compositional and structural information of soot particles is essential for a better understanding of the chemistry and mechanism during the combustion. The aim of the present study was to develop a method to analyze such soot particulate samples with high complexity and poor solubility. Methods:The solvent-free sample preparation matrix-assisted laser desorption/ ionization (MALDI) technique was combined with the ultrahigh-resolution Fourier transform ion cyclotron resonance (FTICR) mass spectrometry (MS) for the characterization of solid soot particulates. Moreover, a modified iso-abundance plot (Carbon Number vs. Hydrogen Number vs. Abundance) was introduced to visualize the distributions of various chemical species, and to examine the agreement between the hydrogen-abstraction-carbon-addition (HACA) mechanism and the polycyclic aromatic hydrocarbon growth in the investigated flame system. Results:This solvent-free MALDI method enabled the effective ionization of the solid soot particulates without any dissolving procedure. With the accurate m/z ratios from FTICR-MS, a unique chemical formula was assigned to each of the recorded mass signals. The combustion products were proven to be mainly large polycyclic aromatic hydrocarbons (PAHs), together with a small amount (<5%) of oxidized hydrocarbons. Conclusions:The developed method provides a new approach for the molecular characterization of soot particulates like carbonaceous materials. The investigated soot particulates are mainly PAHs with no or very short aliphatic chains. The growth mechanism of PAHs during combustion can be examined against the classic HACA mechanism.
